kvm-all.c: Move init of irqchip_inject_ioctl out of kvm_irqchip_create()

Move the init of the irqchip_inject_ioctl field of KVMState out of
kvm_irqchip_create() and into kvm_init(), so that kvm_set_irq()
can be used even when no irqchip is created (for architectures
that support async interrupt notification even without an in
kernel irqchip).
